They are trying to transition their audience to streaming; doesn't mean they'll succeed.There is no "magic potion." This is why radio companies, including Cumulus, are transitioning their audiences to streaming, and investing in digital content creation.
By 2036, these companies will be primarily content companies, with the bulk of their revenue coming from things other than broadcasting.
If by digital content creation you mean listener focused digital content creation, count me as underwhelmed. I seldom if ever see any online content from a radio broadcasting company that is of any value, apart from "recently played" logs, which I do find valuable.
Of course, digital advertising vehicles and digital marketing strategy vehicles offered to advertisers is a whole other ballgame. This could be a profit driver but that is a fiercely competitive segment.
